摘　　要：配电网中的间谐波是引起电压闪变的重要原因。针对上述问题,设计了基于巴特沃斯滤波器的并联型有源滤波器,并以上海某港口配电系统的谐波状况为实例进行了仿真研究。仿真结果表明:该有源滤波器能够较好的滤除电网中的间谐波电流,抑制电压闪变。证明了该方案合理,有效。The inter-harmonic in the distribution network causes the voltage flicker. Aiming at this problem, a shunt active power filter based on Butterworth filter was designed. The simulation was run refer to the harmonic condition of a port distribution system in Shanghai. The result shows that the active power filter can eliminate the inter-harmonic current and voltage flicker in the network and the scheme is effective.

关 键 词：间谐波 闪变 巴特沃斯滤波器
